FAUCET-FILTER.

SPECIFICATION forming part of Letters Patent No. 427,029, elated April 29, 1890. Application led May 16, 1889. Serial No. 311,024. (No model.)

To all whom t may concern,.-

Beit known that I, FRANK BARDEZ, a citizen of France, residing at San Francisco, in the county of San Francisco andState of California, have invented a new and useful Faucet-Filter, of which the following is a specification.

The obj ccts of my invention are to provide a faucet of simple construction, compact form, low cost of manufacture, and at the same time au effective, self-cleansing', and easilyrenovated water-filter.

The nature of my improvements is fully set forth in the following` description, reference being' had to the accompanying drawings, in which- Figure l is a vertical longitudinal section of my faucet as it appears when the water is shut off, the inside partsbeing shown in elevation; Fig. 2, a like View, showingL how the plug is rotated in orderto obtain filtered water; Fig. 3, also a similar view, showing how the filter is cleansed; Fig. 4, a cross-section taken on line l l, Fig. 3, looking' from the front; Fig. 5, a side elevation of the faucetplug; Fig. 6, a perspective view of the diaphragm or filtering apparatus; Fig. 7, a horizontal section taken on line 2 2, Fig. 3, looking from the top; Fig. S, a horizontal section taken on line 3 3, Fig. 4, looking downward; and Fig. 9, a broken vertical cross-section giving an enlarged view of part of the plug and plug-chamber.

Similar letters of reference indicate corresponding parts throughout all the views.

A represents the faucet-body; a, recesses within the plug-chamber; B, tapering tubular plug; Z), floor or partition within the plug; c, opening in the plug; d, water-ports; e e', apertures above and below the plug-partition; O, nut; D, washer; E, check-nutvand tip; g g, guides within the plug; F, filtering-frame; h h, segmental anges within the plug; G, cap or plug; Il, handle; I, tap-ring; t', flange of saine.

The body of the faucet A, comprising the shank, the plug chamber or barrel, and the bib, is of the usual construction, except that the barrel is tapering and has inner recesses o, the purpose of which will he better underabove and two below the floor l). tits snugly in the barrel, within which it is my device.

plained.

The plug consists of atapering shell or tube open at the top and bottom and divided into two parts by a horizontal partition or iioor b. Open water-ports d are provided on opposite sides of the plug,correspondi n g with the wate rchannels of the faucet-body. A similar but larger opening c is located about midway between thc water-ports in another face of the plug, the opposite face remaining` unperforated. Below the water-ports and in the same plane are situated other apertures c e-two held by means of a nut O engaging its threaded foot, the washer D preventing any leakage at the bottom. The ornamental tip E serves also as a check-nut. The upper inner portion of the plug has on opposite sides two sets of'guides g g, between which is inserted the diaphragm or filtering apparatus F.

This filter is composed of a light frame or double grating inclosing a slab of pumicestone, a piece of felt, or other `filtering material. The frame is made tapering to conform with the plug, except that part of one side runs down straight and is cut so as to rest upon the lower edge of the opening c. This construction is preferable to a wholly tapering frame, as will be explained hereinafter.

The lilter-frame corresponds in length to the height of the guides g-tliat is to say, reaches from the ioor b up to the segmental iianges 71, 7L, upon which the cap G is seated. The latter is surmounted by a handle H, by means of which the plug is rotated.

The frame F, cap G, and handle IVI, I usually cast of a single piece; but it is obvious that the sides of the frame may be made detachable without yaltering the effectiveness of They could, for instance, be hinged to the under side of the cap G, and have their lower ends united bya clasp, thus presenting as much firmness as when cast solid with the rest. Such a construction might afford an easier means of replacing the filtering material when worn out.

The filter-frame is held within the plug by means of a ring I, slipped over the handle,

The plug IOO the screw-threaded flange of the ring engaging the screw-thread at the upper end of the plug. The c'ap G and handle are of course held down by this same ring.

The parts above described are put up to gether and operated. as follows:

The plug B having been dropped into its chamber in the position shown in Fig. l, the tapering shank of the faucet-body is joined toa water-pipe in the ordinary manner. The filter is then inserted within the plug, being let in between the guides, so that its broader sides face the water-ports (Z and its straight edge abuts on the lower border of the opening c. Care is also taken to have the filtering material project out somewhat of the center of this opening. The filtering apparatus with surmounting cap and handle being in position, the ring I is slipped over the whole and binds the several parts together.

Then the plug is situated as shown in Fig. l, it. will be seen that the unperforated side of the plug lies opposite the water-inlet, and the water is consequently cut ofi. Now, if filtered water is wanted, the handle and parts depending therefrom are given a quarter-rotation and the plug thereby equally revolved. This, as shown in Fig. 2, brings the water-ports d in a line with the passages of the faucet-body and the water is let into the plug,'within which it encounters the filter, where it is rid of its impurities,coming oil through the bib in aclear state. It might be noticed that it the filter-frame were wholly tapering some water would escape unfiltered, as the frame is of less.

breadth than t-he width of the opening c, to which it presents one edge. The filter nec essarily retards the flow, and as the water rushes into the plug it fills up its interior, seeking every outlet. Thus a port-ion of it is carried toward the opening c, and were it not for the sha-pe I give to the filtering apparatus a small quantity of unclean water would find its way around its edge at this spot and mingle with the purified water; but by making that edge of the frame F stra-ight for the greater part of its length and causing it, as well as the filtering material within, to preject into the opening c, as already described, this inconvenience is avoided and a tighter lit of the plug within the barrel insured.

Should it be desired to clean the filter, all there is to do is to give the handle a half-rotation. In that case the water follows a quite different course. (Indicated by the arrows in Figs. 3, Ll, 7, 8, and 9.) It is then let into the plug through the opening c, striking the filter edgewise and washing oft all the impurities that may have collected upon its posterior face. As the bib-channel has been stopped by the half-turn given to the handle and dependent parts, (see Figs. 3 and 7,) the only outlet is through the apertures c. The water consequently passes' through the latter into the recesses (t of the plug-chamber, re-entcrs the plug through the apertures c', and finally comes ofi unfiltered and loaded with gathered impurities at the lower end of the faucet, as illustrated by arrows in Figs. 3, 4, and 9.

From the above description it may be seen that my faucet is composed of but few pieces, easily constructed, of small bulk and little weight, and a thorough self-cleaning filter. It also possesses this great advantage that the filtering material may be renovated at will and in a moment without shutting the water from the mains, as the filter, although con tained within the plug, is wholly independent and detachable from it.

IIaving fully described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a faucet, oi' a tubular rotative plug, a horizontal partition dividing the sam e, vertical guides rising from said par tition to the upper end of said plug, a removable filter engaged between said guides, mental flanges uniting said guides on each side of said filter, a cap for said plug seated upon said flanges, a handle secured to said cap, and a ring to bind said plug, filter, cap, and handle together, substantially as set forth.

2. The combination, in a faucet, ol a plugchamber, a water-inlet connected therewith, a 9

tubular rotative plug fitted in said chamber, an opening in said plug adapted to face said inlet, a filter placed edgewise to said opening, a fioor in said plug beneath said filter, apertures above said floor, recesses within said plug-chamber connected with said apertures, and an outlet below said fioor connected with said recesses, substantially as described.

3. A tubular rotative faucetplug open at both ends and horizontally divided by afioor, having in the upper part oppositely-placed water-ports d, through which water may pass in a straight course, and an opening c midway between said ports, adapted, in connection with other apertures e e above and below said floor, to change the direction ot the water and let it firstinto the upper end of said plug, then into and out of the lower end of the same, substantially as shown, for the purposes specified.

In witness whereof I have hereunto set. my hand and affixed my seal.
